Both myself and my partner have purchased the same crud mudguards. They are genuinely very easy to fit and can be attached in under five minutes. They are fabulous for my partner's bike as it is a newer model with disc brakes. However, my bike is an 8 year old trek with cable brakes. The front mud guard's attachment interferes with the braking system and can't be attached, worth bearing in mind if there's anyone else out there with an older braking system. Once attached to both bikes, they were excellent when going over fairly rough terrain and I would recommend them to friends.
